'Yellow Wire - Stereo Connection???'

Where specifically does the yellow wire connect? Is it to the speaker wires behind the head unit, the power wires, etc.? Can this only be used if you have a mute option on your car? Will I run into the same issue if I purchase the advanced mute wiring kit? niether one of these solutions answered the question... I also have the hcb-30 unit and the same questions.... Can this only be used if you have a mute option on your car? Will I run into the same issue if I purchase the advanced mute wiring kit

    No... havnt installed it yet, the yellow wire is supposed to go to the stereo to mute the radio when the phone rings,,,, but I dont have a "audio mute" input on my stereo.... If I get the advanced mute setup they have it intergates it into the car speakers but does it also take care of muting the sound too?

  • Samuel Charles Spriggs May 11, 2010

    It sounds like the mute kit just switches the speakers from one source to another or just disconnects them. So, I would say, yes, that would mute the sound.

  • Samuel Charles Spriggs May 11, 2010

    The yellow wire is often for a power antenna -- but not always -- there should be a label somewhere.



    The system is working, you just have an extra wire -- is that correct?

Yellow wire connects to the music mute wire on the back of the car stereo (usually brown). This will mute the stereo when the hands free is in use!

Ouku single din no sound from rca cables


Sorry I did not use the video out RCA cables. My audio RCA cables worked fine... I ran them to my JBL amplifier through a conversion adapter. I did not run it direct to the amp.. I used Metra TYTO-01 03-08 Toyota Vehicles Harness for JBL SYS (Ebay item 160560648718) and it worked great.

Here is the wiring color coding that I found online:

If you can help me i need to know if it is possible to wire a amp into a 2002 landcrusier stock headunit cheers


yes, there is an amp turn-on wire from the head unit (black with a red stripe). You will need to add a power wire and fuse from the fuse box to run the amp. You can use the speaker outputs as inputs to the amp, depending on what you are trying to do. Please let me know if you need more help, and identify the amp model as well as the speakers you will connect.

Installing aftermarket Kenwood stereo on 1991 Subaru Legacy. The subaru stock wiring does not have a red ignition wire. Can i simply connect the kenwood ignition wire to the Accessory +12v (Yellow/red)?...


Hi, according to my source, there should be an accessory wire that is blue with a yellow stripe. If your is yellow/red, that's fine. You actually should prefer an accessory wire to an ignition wire as there may be less static on the accessory wire. Just make sure the wire does not have power when the key is off. Don't use the illumination wires--they are not needed for the aftermarket head unit and should be taped off.

Please let me know if you have questions, and thanks for using FixYa.

Radio Constant 12V+ Wire: Orange yellow
Radio Ignition Switched 12V+ Wire: Yellow red
Radio Ground Wire: Black/White black

Left Rear Speaker Wire (+): Brown green

Right Rear Speaker Wire (+): Dark Blue purple
Right Rear Speaker Wire (-): Light Blue purple/black
parking brake: blue light green

For this last wire, access the back of the parking brake to find a switch with a blue wire. Peel some insulation from the wire and wrap the stripped end of a 3 foot piece of 16 or 18 gauge wire around the stripped section. Solder and wrap the connection with electrical tape, route the wire to the jvc, then strip and solder the other end to the pigtail of the head unit.

If you are also installing a camera seeing behind you when backing, you will need to run a wire to the back-up light on the driver side reverse light (light green) wire along with your video cable.

Someone gave me a Pioneer DEH-2700 head unit and didn't have any of the manuals. I have a 2007 Chevy Cobalt How to I install this unit into my car. I don't know which wires go to what or anything


the easiest way to solve this issue is to buy a wire harness for your car this will make the install alot easier. Its already color coded for your wires, so head out to your local installer or try best buy you might also need a stereo kit. Email me with questions on installs. jerree_cardenas2006@yahoo.com
